One of the world’s largest cities Is quietly Disappearing. In 2025 and early 2026, NASA’s powerful NISAR satellite. A joint mission with India’s ISRO, captured something remarkable: Mexico City sinking in near real time. Mapping the city’s ground movement every 12 day. The satellite revealed that parts of the city are subsiding at a rate of 0.78 inches every single month. That adds up to nearly 10 inches per year on average, with some zones dropping as much as 20 inches annually. Read More…
“You can see the full magnitude of the problem,” said NISAR scientist Paul Rosen. The data showed dark blue zones representing the fastest sinking areas spread across the city’s most critical infrastructure, including the main international airport and the iconic Angel of Independence monume
How Deep Has It Already Fallen?
The scale of the sinking that has already occurred is staggering. Over the past century alone, parts of Mexico City have dropped more than 39 feet (12 meters). The Metropolitan Cathedral, whose construction began in 1573, now visibly tilts to one side — a silent, stone witness to the ground slowly disappearing beneath it.
“We have one of the fastest velocities of land subsidence in the whole world,” said Enrique Cabral. A geophysics researcher at the National Autonomous University of Mexico.

The Root Cause: Thirst Beneath the Surface
The primary driver of this crisis is ground water over extraction. Mexico City relies too much pumping water from the ancient aquifer trapped beneath the old lakebed. As water is pulled out the soft clay compresses and shrinks causing the land above it to sink. It is a vicious cycle the more water the city needs the faster it sinks. Experts now warn that the shrinking aquifer could also lead to a catastrophic water shortage in the near
The Hidden Cost: Crumbling Infrastructure
The sinking is not just a geological curiosity it is tearing the city apart from below. Roads crack and warp. The subway system suffers structural stress. Water and sewage pipes fracture, causing leaks and contamination. Housing becomes unsafe. According to researcher Cabral, “It damages part of the critical infrastructure of Mexico City, such as the subway the drainage system the water system housing and
A Global Crisis, But Mexico City Leads the Decline
Mexico City is not alone. Jakarta , Manila , Bangkok, and even New York City are all sinking to varying degrees. The World Economic Forum estimates that the global economic exposure to land subsidence is a staggering $8.17 trillion roughly 12% of global GDP. However, Mexico City stands out as one of the fastest sinking major cities anywhere on the planet.
Can It Be Stopped
There is no easy fix. Scientists agree that the first step is understanding the problem in precise detail which is exactly what the NISAR satellite is now enabling. Future research aims to track subsidence building by building, giving city planners the data they need to act. Reducing groundwater extraction improving water distribution infrastructur and investing in resilient construction are all part of the solutionIn 2025 and early 2026.

But time is running short. As Cabral soberly put it: “To do long term mitigation of the situation, the first step is to just understand.”
Mexico City is not disappearing overnight. But beneath the noise of 22 million lives, the ground is silently giving way — one centimetre at a time.
